The 36 Best Trillion-Shaped Engagement Rings of 2021

There are certain stone shapes that instantly come to mind when dreaming about an engagement ring—emerald, oval, cushion, pear, round, and princess cuts are all-time favorites from platinum and yellow-gold settings to contemporary takes set in rose gold or a mix of metals. Then there are more uniquely shaped engagement rings which have become increasingly popular with modern brides from colored stones to hexagon shapes and east-west settings. If you’re the type to feel drawn to the latter, trillion-shaped stones are a stunning and unique style of engagement ring to consider.

If you’re the type of gal who’s set on a sizable diamond or gemstone (no shame in the game) but may not have the budget to spend on three or four (for five) carats, a trillion ring is a great way to go. In terms of sparkle, a shallow diamond does typically result in less brilliance which means a trillion cut may not be the most glittery ring in the bunch, but it will certainly sparkle and shine on your finger.

You may be more familiar with trillion-shaped stones as accents to more popular cuts like emerald or square diamonds and gemstones, but the triangular shape—which, fun fact, was originally created in the Netherlands—is beyond striking as the main event whether as a solitaire or multi-stone ring. You’ll find the three-sided stone available with round or pointed edges (aka curved or uncurved) and available in a range of unique settings whether you’re drawn to a two-stone ring, a double band, an off-kilter mounting, or halo accent.

What to Look for When Choosing a Trillion-Shaped Engagement Ring

Stone

Not only are trillion cuts eye-catching, but they also offer plenty of benefits. "Trillion-cut diamonds offer a high degree of brilliance and fire, and the cut can also hide inclusions fairly well. The superior hardness of diamond makes it a durable and reliable stone for everyday wear. There are also many other trillion-cut gemstones that would make for interesting engagement rings. Sapphire is a durable gemstone that comes in a variety of colors, and gems like morganite and ruby are also popular as engagement ring stones," suggests Kim Kanary. "It's important to be careful with less durable stones in rings, but a secure setting and continual care can help ensure your stone is protected for a lifetime!"

Setting

Due to their more fragile nature, it's important to select a setting that protects your trillion-cut stone from wear and tear. "Because trillion cuts have three pointed ends, they can be susceptible to durability issues," Kanary warns. "Thus, it's important to find a setting that protects those three termination points to avoid any chipping. Some trillions are actually cut with curved edges to avoid this issue, which means you can rest a little more secure regarding the durability of your stone."

Style

If you're a bride who is considering a trillion-cut engagement ring, you're already unafraid to step outside of the box. Whether you opt for something daring and bold or something more minimal, embrace your personal style while being mindful of design aspects that will keep your stone safe. "One of the most exciting aspects of selecting an engagement ring is that it can be completely unique to your personal tastes! The style can be everything from a simple solitaire, to an asymmetrical two-stone ring, to a solitaire with a halo and pavé diamonds," says Kanary. "Make sure to consider how your preferences can be achieved while ensuring the style of the ring protects your trillion-cut diamond, as the points of the triangular cut can be vulnerable to chipping."

FAQS

Are trillion-cut diamonds more expensive than a round or cushion-cut diamond? "Round brilliant diamonds, because of their high demand, typically hold the highest price per carat on the market. All other factors being equal, trillion-cut diamonds will be less expensive than rounds and most other cuts due to their lower demand," Kanary explains.
What are the benefits of selecting a trillion-cut diamond? "One great benefit to choosing a trillion-cut diamond is that it has a larger face-up surface than almost any other diamond. So, a one carat trillion-cut diamond is going to look bigger than nearly any other one carat diamond. Because of its lower price per carat, you are able to get a much bigger-looking diamond for a better value, all other quality factors being equal," states Kanary.
Are trillion-cut diamonds rare? "Trillion cuts are rare in the sense that they aren't as plentiful in the market, but that is more so due to the lower demand for them and less about their availability as a natural resource. If there was a sudden surge in popularity, then trillion-cut diamonds would quickly lose any semblance of rarity," Kanary informs.
How many facets do trillion-cut diamonds typically have? "Trillion-cut diamonds are triangular diamonds with three equal-length sides and a flat table facet. Trillion cuts can have anywhere from 31 to 50 facets depending on how the stone will be set. Stones used as center stones typically have more facets and a more convex or rounded shape to them," says Kanary.
Do trillion-cut engagement rings hold their value? "If you consider the four C's in diamond grading—cut, clarity, color, and carat weight—they all have a coordinating impact on the diamond's value. When it comes to cut, the quality of the cut is much more important than the type of cut. The value of the type of cut is largely dependent upon what is currently trending," Kanary advises. "The good news is that all things being equal, they can be less expensive than other diamond cuts. This also means that you may purchase a trillion-cut engagement ring, and future popularity could greatly increase its market value."
